CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a SQL injection flaw in SourceCodester Dynamic Input Field Generator 1.0. It exists in the saveUser function of /public/submit.php where the Researcher argument is improperly handled. The issue allows remote attackers to inject malicious SQL queries due to lack of input validation. A public exploit is available.

Detection Guidance

Check the submit.php file for improper input handling in the saveUser function. Look for code that processes $_POST['person'] without validating array types. Use grep to search for vulnerable patterns like 'saveUser' or 'submit.php' in your web directory.

Impact Analysis

An attacker could exploit this to manipulate or extract sensitive data from the database. It may allow unauthorized access to user information, modify existing data, or delete records. The application's error handling could also be bypassed, making attacks harder to detect.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality requirements. For HIPAA, it may compromise protected health information security. Both standards mandate proper data protection measures which this flaw undermines.

Mitigation Strategies

Implement strict input validation to ensure $_POST['person'] contains only non-empty strings. Reject submissions with nested arrays or invalid data types. Update the saveUser function to validate input before processing.
